Description

Method and terminal for setting happy bit on uplink enhanced control channel

The present invention relates to the field of resource scheduling on a Uu interface (an interface between a base station and a terminal) in a Wideband Code Division Multiple Access (WCDMA) communication system, and more particularly to an uplink enhanced control channel. (E-DCH Dedicated Physical Control Channel, E-DPCCH) The setting method and terminal for the happy bit (hereinafter referred to as Happy bit).

Background technique

In the existing system, the wireless side uplink enhancement technology is introduced, and the High Speed Uplink Packet Access (hereinafter referred to as HSUPA) function is implemented. HSUPA uses physical layer fast retransmission and soft combining (Hybrid Automatic Repeat request, hereinafter referred to as HARQ), Node B (NodeB) distributed scheduling, and shorter transmission time interval (hereinafter referred to as Transmission Time Interval). For the ΤΤΙ and high-order modulation technologies, the maximum uplink data throughput rate of a single cell reaches 5.76 Mbit/s, which greatly enhances the data service carrying capacity and spectrum utilization of the WCDMA uplink. In order to support HSUPA, the Media Access Control (MAC) layer includes MAC-es/MAC-e entities, so that each terminal has its own enhanced uplink dedicated transmission channel (Enhanced Dedicated Channel, E) connected to the NodeB. -DCH ). In order to enable the E-DCH to support the variable radio link control protocol data unit (RLC PDU) size, a MAC-is/MAC-i entity is introduced in the MAC, so MAC-is/ The MAC-i also supports the E-DCH function. In order to support HSUPA, the physical layer adds an uplink enhanced control channel (E-DPCCH) and an E-DCH Dedicated Physical Data Control Channel (E-DPDCH) to the uplink, and adds a downlink absolute grant channel (E). -DCH Absolute Grant Channel (E-AGCH), E-DCH Relative Grant Channel (E-RGCH) and E-DCH HARQ Acknowledgement Indicator Channel (E-HICH). The E-DPDCH is used to carry the uplink transmission data of the HSUPA user; the E-DPCCH is used to carry the accompanying signaling of the demodulation uplink enhanced dedicated data channel (E-DPDCH); Common channel, the cell where the E-DCH radio connection is served by the user indicates the maximum available power offset of the E-DPDCH of the UE, usually a slow adjustment; E-RGCH is a dedicated channel, and the UE can be quickly adjusted in 2 ms. Equipment, user equipment) uplink available power; E-HICH is used to feedback whether the user receives the correct ACK/NACK information of the process data.

The Happy bit in the E-DPCCH is used to indicate whether the terminal is satisfied with the current Service Grant (hereinafter referred to as SG). In the case of single carrier, if the following three unhappy criteria are met at the same time, the terminal will indicate unhappy. If not satisfied at the same time, the terminal will indicate that the current service is happy (happy):

1. The scheduling data being transmitted by the terminal is equal to the maximum scheduling data allowed by the current SG; 2. The terminal has sufficient available power to transmit higher rate data;

3. In the same 与 as the Happy bit, the same power offset is selected based on the enhanced uplink transmission format combination (E-TFC) to select the power offset. The SG multiplies the ratio of the number of activated HARQ processes to the total number of HARQ processes to send data. The total E-DCH Buffer Status (hereinafter referred to as TEBS) will request a request greater than the happy bit delay condition (Happy_ Bit— Delay— Condition, in ms.

For the deactivated process condition 1 is always true. For lOmsTTI, the ratio of the number of activated HARQ processes in Condition 3 to the total number of HARQ processes is always 1.

Condition 2, in order to estimate whether the terminal has enough available power to support a higher data transmission rate, the terminal will judge according to the following two criteria:

a) If MAC-i/MAC-is is configured, determine E-TFC so that the transport block size is at least 32 bits larger than the transport block of the selected E-TFC in the same TTI as the Happy bit, if MAC-i/ is not configured. Is, determines the E-TFC, so that the transport block of the selected E-TFC in the TTI whose transport block size is the same as the Happy bit is at least a large X bit, where X is not all of the non-scheduled MAC-d flows and there is data in the cache The size of all configured minimum RLC PDUs on the logical channel.

b) in the same TTI as the Happy bit, transmitting data based on the same power offset as the selected power offset in the E-TFC selection, checking whether the identified E-TFC (ie, the E-TFC determined in a) is supported, For example, it is not blocked. The current system specifies the meaning of the value of the Happy bit, see Table 1:

Table 1 Mapping of single carrier Happy bits

The NodeB scheduler can know whether the terminal transmits at the maximum allocated power according to the Happy bit on the E-DPCCH, thereby determining whether to increase, decrease, or maintain a given terminal allocated power. If the Happy bit on the E-DPCCH is unhappy, the NodeB may increase the terminal allocation power. If the Happy bit on E-DPCCH is happy, NodeB can only reduce or maintain the power allocated by a given terminal. If the current transmit power of the UE in multiple TTIs is lower than its current maximum value, its allocated power should be reduced.

As a supplement to the dual cell-high speed packet access (DC-HSDPA) of the downlink dual cell, two carrier aggregation technologies are introduced in the uplink. The dual carriers belong to the same NodeB and are adjacent carriers. The total number of HARQ processes on the two carriers is equal. The operation is used to configure at least two carriers simultaneously in the downlink. Since the uplink is a dual carrier, for each E-DCH transmission, the network side needs to process two E-DPCCH physical channels simultaneously, and the terminal has two Happy bits to report. If the happy state of the terminal is still set according to the single-carrier unhappy criterion of the current system, the terminal on one carrier is happy, and the terminal on the other carrier is unhappy. At this time, the NodeB cannot determine the happy state of the terminal.

The happy bit is set to unhappy, indicating that the terminal is not satisfied with the current service authorization. If not, the terminal will set the happy bit to happy, the conditions are specifically:

Condition 1, there is at least one carrier, the amount of data that the terminal is transmitting on the carrier is equal to the maximum amount of scheduling data allowed by the current SG in the E-TFC selection on the carrier, and the terminal has sufficient power on the carrier to transmit a higher rate. The data.

Where the following criteria are met, al, bl indicates that the terminal has sufficient power on the carrier to transmit higher speed data:

Al) If MAC-i/is is configured, the E-TFC of the carrier is identified, so that the identified E-TFC transport block size is at least one greater than the transport block of the selected carrier E-TFC in the same TTI as the Happy bit. The fixed value, where the given value is greater than or equal to 16 bits, if MAC-i/is is not configured, the carrier E-TFC is identified, so that the identified E-TFC transport block size is selected in the same TTI as the Happy bit. The transport block of the carrier E-TFC is at least X bits, where X is the smallest RLC PDIL of all configurations on all logical channels belonging to the scheduled MAC-d flow and having data in the buffer

Bl ) In the same Happy as the Happy bit, the data is transmitted based on the same power offset as the selected power offset in the E-TFC selection, checking whether the identified E-TFC is supported (ie the carrier E-TFC identified in condition a) ), for example, not blocked, if supported, means that the criterion bl is met.

The carrier can be a primary carrier and/or a secondary carrier.

When both the primary carrier and the secondary carrier satisfy that the amount of data being transmitted is equal to the maximum amount of scheduled data allowed by the current SG in the E-TFC selection on the carrier, the terminal may be judged according to the above criteria a1 and bl respectively. In addition to having sufficient power on the carrier and the secondary carrier to transmit higher rate data, it can also be judged according to the following criteria a2, b2.

Delay condition Happy — Bit — Delay — Condition time.

When the carrier is the primary carrier and the secondary carrier, the SG of the current primary carrier is multiplied by the ratio of the number of processes that activate HARQ on the primary carrier to the total number of HARQ processes, and the SG of the current secondary carrier is multiplied by the number of active HARQ processes on the secondary carrier and the total number of active HARQ processes. The sum of the ratios of the number of HARQ processes is transmitted, that is, the number of HARQ processes/the total number of HARQ processes on the SG primary carrier of the primary carrier + the number of HARQ processes activated on the secondary carrier SG χ secondary carrier/the total number of HARQ processes are transmitted, TEBS will request a time greater than Happy—Bit — Delay— Condition ( ms ).

When the carrier is the primary carrier and the secondary carrier, the sum of the SG of the current primary carrier and the SG of the secondary carrier is multiplied by the ratio of the number of activated HARQ processes to the total number of HARQ processes, that is, (the SG of the primary carrier) + SG of the secondary carrier χ Activate the number of HARQ processes/total number of HARQ processes for transmission.

If the terminal satisfies the above conditions 1 and 2, the terminal will set the Happy bit to the unhappy state. If it is not satisfied at the same time, the terminal will set the Happy bit to the happy state, as shown in Table 2. Table 2 Happy state judgment of the terminal in DC mode
